CHARLES A. STENIUS, OF SOUTH BEND, INDIANA.

JAR.

To all whom it may concern:

Be it known that I, CHARLES A. STENIUs, citizen of the United States, residing at South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Jars, of which the following is a specification.

My invention relates to the improvement of ars or receptacles for fruit or similar substances, and the objects of my invention are to provide a jar of this character with improved means for hermetically sealing the same; to so construct the jar and its closure as to admit of the jar being quickly and eflectively closed and to produce other improvements in details of construction and arrangement of parts which will be more fully pointed out hereinafter.

These objects I accomplish in the manner illustrated in the accompanying drawing, in which:

Figure 1 is a view partly in elevation and partly in section of my improved jar and cover, Fig. 2 is a plan view of the jar with cover attached showing a portion of the cap ring broken away for the sake of clearness in illustration, Fig. 3 is a detail sectional view on line :ca' of Fig. 2.

Similar numerals refer to similar parts throughout the several views.

1 represents a jar which may be of glass or other suitable material and which in its upper portion is provided with a rounded peripheral projection '1, the head or up er end of the jarterminating in a prefera ly rounded portion 1 between which and the portion 1 is formed a peripheral recess 1 In order to admit of the jar being formed without unequal shrinkage or unequal hardening of the glass, I produce that portion of the jar which is provided with the rounded projection 1 of corresponding thickness with the remaining wall portions.

2 represents a cap or cover plate which is preferably of glass, this cover plate having the general outline of a disk and provided on its underside at a distance from its outer edge, with a short downwardly projecting flange 3. The laterally extending flange of the top plate or that portion which is above and on the outer side of the downwardly Specification of Letters Patent.

groove or seat 5 in which is designed to rest a rubber ring or gasket 6. As shown in the drawing, the downwardly flanged portion 3 of the cap plate is designed to extend and fit within the upper edge of the jar, while that portion of the cap plate which extends on the outer side of the flange 3, is adapted to bear and be pressed upon the gasket 6 in the manner illustrated more clearly in Fig. 1 of the drawing.

In order to hold the cap or cover plate in its osition on the ar and to form a perfect sea for the jar, I provide a metallic sealing ring 7 which is substantially of an angular form in cross section and the upper horizontal member 7 a of which bears upon the upper side of the outer portion of the cover plate 2. The downwardly extending member 7 has formed on the inner side of its upper portion a circular row of indentations resulting in the formation of rounded external projections 8. Below and in vertical alinement with each of the rounded indentations 8, I form in the ring member 7 a rounded recess 9, which recesses result in the formation of the substantially vertical outwardly projecting ribs 9 Below this vertically recessed portion, the ring member 7 terminates in an inwardly and thence outwardly projecting lip 10.

It will be understood that the ring plate 7 is locked into connection with the cover plate 2 by pressing said ring over the outer portion of said cover plate. The projecting studs 4 of the cover plate, follow the elongated recesses 9 and finally enter and engage the indentations 8. hen the jar is being closed, it will also be understood that the outturned terminal portion 10 of the ring 7 will first be s rung outward over the projection 1 of t 1e ar and thence into engagement with the peripheral recess 1 of said jar, in which recess I may if desired, employ a second rubber gasket such as that shown at 6, thus providing a side as well as a top sealing means. It all be seen that the locking of the ring into engagement with the projections of the cover plate and the locking of the terminal portion of the ring into engagement with the jar recess, will serve to hold 1 said cover plate not only in a firm position on extending flange 3, has formed thereon at l the jar, but under such pressure against the suitable intervals short projecting studs 4.

gasket 6 as to eflectually seal the jar against As indicated in the drawing, the upper end the entrance of air.

of the jar 1 has formed therein a continuous Owing to the fact that the cover together with its cap ring is so formed as to be pressed quickly into place over the jar and to become immediately locked thereon, it is obvious that the necessity of following the practice of crimping the metallic cap ring after the cover is in place, is obviated.

As indicated at 11, I provide the ring member 7 with one or more downwardly extending tongues which may be shaped to conform to the outline of the upper portion of the jar and the tapering lower end of one of which is adapted to be engaged in the slotted opening 12 of the usual form of detached key 13. The stem of this key being turned in the usual manner, it is obvious that the tongue 11 together with a sufficient portion of the cap ring will be wound about said stem to permit of the ready removal of said cap ring and cover.

From the character of the inclosure described herein, it will be understood that any person may by exerting ordinary strength or pressure, quickly and effectively seal a jar.

It will be understood that the receptacle herein described may be in the nature of a square or oblong box instead of the round jar form shown.

What I claim, is: 1. A jar cover comprising a body portion having a plurality of projections formed about its upper edge in combination with a ring having a plurality of recesses formed therein into which said projections are adapted to enter and a plurality of additional recesses adapted to guide said projections into the first named recesses.

2. A jar cover comprising a body portion having a plurality of projections formed around its upper edge, in combination with a ring comprising a horizontal portion and a downwardly extending portion, the latter having a plurality of recesses formed therein into which said projections are adapted to enter and also having a plurality of elongated guide recesses adapted to guide said projections into said first named recesses and a yielding gasket on said body portion.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES A. STENIUS.
